    Cause & solution for BMI270 dl_err?

    Hi,
    Sometimes during motionless SENS error compensation (CRT) we encounter a "dl_err".

    Could you please explain what causes this and how we can either avoid it or recover and continue with calibration?

    Thanks!
    Richard.

    From the BMI270 spec, dl_err means download of 2KB configuration stream fail.  please give more information below :

    1. When did you run the CRT? While running CRT, is something else running? For example FIFO.
    2. Did you use the API of BMI270?
    3. Please provide more about  prcocess from power to CRT fail.

    Hi shellywang,

    Thanks for your questions --- these prompted me to review our calibration methods and also to ensure we performed a soft reset of the BMI270 before performing the calibration.  I'm pleased to say it seems to be working reliably now.

    Thanks,
    Richard.
